door hinge backing plates - The 1947 - Present Chevrolet & GMC Truck Message Board Network

hello,

managed to strip the three lower backing plates on my 65 c10. Too the plate out and welded three nuts on the back. fabbed a new retainer, welded it in place and all well.

now installing the door back on, seems two of the top screws stripped. looks a little more involved to get to the backing plate.

any suggestions?

How about using a tap to chase the threads? Sart by using one that is the same size as the factory threads to see if it cleans things up enough to work with.

You could install a Heli-Coil without removing the plate.

I brazed up the holes some and re-taped

I should have posted back here. A friend was over my place helping with some body work. He went in my tool box when I was not looking and took a 3/8-16 tap. He grabbed my cordless makita drill. I was occupied, so I had no idea what he was doing. Next he sprayed wd40 on the holes and screwed the tap in the hole. It cut perfectly clean threads on the plate. After I heard the third, I stopped what I was doing and walked around to see what he was up to. He said he knew I was going to worry about those keepers behind the plate and I just needed to try this. It worked great and the threads are strong. Only problem now is getting the 1 1/2" 3/8 fender bolts since they are 1.50 each.

Wish I would have tried this before welding nuts on the back of the first plate.
